ABSTRACT There is a need to develop a new low cost indigenous electronic cradle because the existing cradles are imported and costly. This paper presents the design and implementation of a new indigenous low cost E-Baby Cradle that swings automatically when baby cries, for this it has a cry analysing system which detects the baby cry voice and accordingly the cradle swings till the baby stops crying. The speed of the cradle can be controlled as per the user need. The system has inbuilt alarm that indicates the condition – when baby does not stop crying with in a stipulated time, which intimated that baby needs attention. This system helps parents and nurses to take care of babies without physical attention by already recorded voice input to FN-M16P model and at this same time Cradle also moves according to the user need. 1. INTRODUCTION To describe and validate a non-contacting sensor that used reflected ultrasound to separately monitor respiratory, onrespiratory, and caretaker movements of infants. Anin-phase and quadrature (I & Q) detection scheme provided adequate bandwidth, in conjunction with post IDL - International Digital Library
detection filtering, to separate the three types of movement. The respiratory output was validated by comparing it to the electrical activity of the diaphragm(Edi) obtained from an infant ventilator. The non-respiratory movement output was compared to movement detected by miniature accelerometers attached to the wrists, ankles, and heads of infant. Caretaker movement was compared to Audio observations annotated in the recordings. The respiratory rate determined by the sensor was equivalent to that from the Edi signal. The sensor could detect the increase and decrease movement of chest of infant while breathing. Non-respiratory movement was identified with an agreement of 0.9with the accelerometers. It potentially interfered with the respiratory output an average of 4.7+/−4.5% and 14.9+/15% of the time in infant not requiring or on ventilator support, respectively. Caretaker movements were identified with 98% sensitivity and specificity. The sensor outputs were independent of body coverings or position.

Parents in the present world are busy in their professional life, so they do not get sufficient time to take care of their babies. It may be expensive for the household to afford a nanny. Today’s woman has to manage home along with their office work simultaneously. After long working hours, they have to take care of the home along with the baby. They may not get enough time to swing the cradle manually and sooth the baby.

Also Hospitals have neonatal and maternity units. Nurses in these units have to take care of many babies. Working:The system is microcontroller based that is being designed is aimed to help parents and nurses in infants care. Features being: 1. Cradle starts swinging automatically when baby cry and swings till the baby stops crying and at the same time recorded voice ( jogula or laalihaadu or voice of mother to console the infant) will play through the FNM16P model. A sound detector is interfaced to the controller which senses sound when baby cries and activates the controller with its digital output. 2. Selection of different voices from Free Android app if baby cries for more than a stipulated time indicating that baby needs attention. 3. Single motor are interfaced via a DC motor driver to the controller. That motor is to swing the cradle when baby cries. 4. Bluetooth interface Receives alert from android app based handsets to change the voice of parents/nurses. An ALCD is interfaced to the controller which keeps displaying the status as messages.

LITERATURE SURVEY The most common methods for measuring respiratory activity involve contacting systems, such as impedance plethysmography or an attachment of a sensor of flow to the airway. Noncontacting methods are useful when no contact is desired or possible. These include the use of pressure mattresses, radar, infrared imaging of warm expired gas, ultrasound methods of detecting airflow at the face, or reflected ultrasound from the underside of a mattress. Non-contacting sensors are especially useful for sleep apnea detection, and have been used in infants for synchronization of a mechanical ventilator with spontaneous breathing efforts even when a patient has an artificial airway or must wear nasal prongs with largeleaks in the airway-infant interface. Description of the Sensor, Circuitry, and Algorithm The ultrasonic sensor head consisted of a transmitter and a receiver placed 15–50 cm above the infant, approximatelycentred over the torso of the infant, mounted either on the ceiling of the isolate with silicone suction cupsor on a bracket attached to an 3|P a g e

open crib or radiant warmer bed. The sensor could be moved several centimetres toward the head or the toes without a change in function. The infant was nursed in the usual coverings or bundled in blankets. The sensor head was attached to an electronics unit by shielded cables, and data were acquired with a laptop computer. Respiratory effort: We compared the sensor respiratory output, to the electrical activity of the diaphragm, or Edi, as determined by a commercially available mechanical ventilator(Servo-i, Maquet Corporation, Solna, Sweden) as an independent reference for respiratory effort. Non-respiratory Movement: We compared the sensor movement output of the algorithm to non-respiratory movements as detected by an independent system of miniature accelerometers. The summed signal from each of the five accelerometers attached to the four limbs and head were then summed, so that a single signal represented any nonrespiratory movement in any of the accelerometers.

It saves time. Manual operation has been reduced to major extent. Less man power required.
Efficient distribution system. Easy to use. Efficient and reliable. My main motive is to eliminate the paper based records using smart phone.
24/7 security and peace of mind for mothers and staff. Prevents kidnap in hospitals. All time protection even if the baby moves around without being noticed by elders, since if it goes near any electric items the sensors help in sending alarms. CONCLUSION The project is designed using structured modelling and is able to provide the desired results. It can be successfully implemented as a Real Time system with certain modifications. Science is discovering or creating major breakthrough in various fields, and hence technology keeps changing from time to time. Going further, most of the units can be fabricated on a single along with microcontroller thus making the system compact thereby making the existing system more effective. To make the system applicable for real time purposes components with greater range needs to be

implemented. We have described and validated a single, ultrasonic sensor for respiratory, accelerometer sensor for nonrespiratory, and caretaker movement in infants in an intensive care setting by using FN-M16P. The cry detector sensor could detect crying of the infant. The nonrespiratory movement output had an agreement of 0.9 with an independent measure of movement by accelerometers. The detection of caretaker movement had a sensitivity and specificity of 0.98 compared to visual annotation of caretaker movements during our recordings. The separate outputs for the non-respiratory and caretaker movements may be useful for a number ofother applications for the clinical assessment of infants and their care. The sensor described was used in infants for this validation. With modifications in the design of the sensor head and postdetectionfiltering, it could be used in older children and adults. The sensor, as part of a synchronizer for adult and paediatric ventilators, could promote the present trend to use noninvasive ventilation as an alternative to invasive ventilation.
